Abstract
A hydraulic axial piston machine (1) is described, the machine comprising a housing, a cylinder block (2) rotatably mounted in the housing about an axis or rotation (7) and having at least one cylinder (3), and a valve arrangement (4) between the cylinder block (2) and the housing, the valve arrangement having a first part (4) rotating with the cylinder block (2) and a second part mounted stationary with respect to the housing. Such a machine should have a high efficiency. To this end the first part (4) comprises an elastically deformable spring section (9).
Claims19
A hydraulic axial piston machine comprising a housing, a cylinder block rotatably mounted in the housing about an axis of rotation and having at least one cylinder, and a valve arrangement between the cylinder block and the housing, the valve arrangement having a first part rotating with the cylinder block, characterized in that the first part comprises an elastically deformable spring section, wherein the spring section and the first part are one piece, and wherein the spring section is machined out of the first part.
A hydraulic axial piston machine comprising a housing, a cylinder block rotatably mounted in the housing about an axis of rotation and having at least one cylinder, and a valve arrangement between the cylinder block and the housing, the valve arrangement having a first part rotating with the cylinder block, wherein the first part comprises a support plate and an elastically deformable spring section, wherein the spring section lies in the plane of the support plate, and wherein the spring section is machined out of the first part.
A hydraulic axial piston machine comprising a housing, a cylinder block rotatably mounted in the housing about an axis of rotation and having at least one cylinder, and a valve arrangement between the cylinder block and the housing, the valve arrangement having a first part rotating with the cylinder block, wherein the first part comprises an elastically deformable spring section, wherein the spring section and the support plate are one piece, wherein the spring section contacts an uppermost surface of the cylinder block, and wherein the spring section is machined out of the first part.
